When only a subset of cells in the mesh are being deformed in a single direction, the pressure and temperature are not consistent. Compressing these cells for a closed domain causes the temperature in them to decrease when it should increase.

I'll be on vacation for the next three weeks; I'm uploading a version that works. I also tried to make a version of the kivaTutorial that uses fvMotionSolverEngineMesh, but couldn't figure the right boundary condition for piston. You'll need to copy over the otape17 file.

I'll be on vacation for the next 3 weeks, so I won't be monitoring/replying until I get back on the 25th. Cheers and thanks for looking into this!
